periodontal scaling

Objective: To study the effects of periodontal scaling on microorganism in periodontal pocket and gingival crevicular fluid in patients with periodontitis.

目的：探讨牙周洁治对人牙周炎袋底微生物和龈沟液量的影响，为研究牙周洁治机制提供依据。

There were no significant differences of the GBF, BCV, BC value and clinical indices of group CP, group AgP and group G between periodontal scaling after 1 week and after 1 month.

治疗后1个月时各组GBF，BCV和BC和牙周临床指标与治疗后1周时无显著性差异。

Periodontal scaling should combine with oral hygiene instructions and methods of plaque controlling daily.

牙周洁治必须和口腔卫生教育、正确的日常菌斑控制措施结合进行。

Objective To study the biological effects of periodontal scaling on gingival blood flow ( GBF)、 blood current velocity ( BCV) 、 blood concentration ( BC) in gingiva and the effects on different clinical indices.

目的探讨牙周洁治和刮治对牙龈血流量（GBF）、血流速度（BCV）和血浓度（BC）等微循环指标和牙周临床指标的影响。

Conclusion: Periodontal scaling can decrease the percentage of pathogenesis bacteria in periodontal pocket bottom and decrease PD, GI and GCF values.

结论：牙周洁治对人牙周炎袋底微生物有明显的改善作用，可通过减少袋底致病菌比率和降低PD以减轻牙周炎症和减少龈沟液的分泌。
